Tolerance Specifications for Perforated Products

Standard Quantity Tolerances

When you request a quote, if you do not specify a tolerance for quantity, McNICHOLS provides the ’exact’ quantity you requested. On large orders, you can lower cost by specifying ’standard’ tolerances. ’Standard’ tolerance is +/- 10% (plus or minus 10 percent). On an order of 50 sheets with a ’Standard’ tolerance, you would receive at least 45 sheets and no more than 55 sheets.

Perf-PanlTM starts out as a coil and is then punched by a die to form the shape of the hole. The die is round and has an indent that creates a dimple in the sheet with a hole in the bottom of the dimple. McNICHOLS carries steel Perf-PanlTM in one stock size (others available by special order).

The holes in Perf-PanlTM are indented and perforated. Hole size is the diameter of the perforation located in the center of the indent. Perf-PanlTM is manufactured in 1/4 inch hole size. The holes run in a straight row pattern.

Perforated sheets contain holes and material. Open area is the total area of the holes divided by the total area of the sheet and is expressed as a percent. In other words, open area describes how much of a sheet is occupied by holes. If a perforated sheet has 60 percent open area, then 60 percent of the sheet is holes and 40 percent is material.

Perf-PanlTM comes in one holes size and associated open area shown below:

Thickness is the measurement from the top surface to bottom surface of the material. Gauge is the most common measurement, but thickness can also be measured in fractional inches or millimeters. This gauges and weights chart can provide additional information.

Quantity is the number of full sheets or cut pieces you need. Unless otherwise specified, the standard tolerance on quantity is “Exact Quantity.” In other words, McNICHOLS will deliver the exact quantity you specify.

Length is the overall measurement of the long side of the sheet; width is the overall measurement of the short side of the sheet. Note that mill tolerances for length and width apply to stock sheets unless otherwise specified. If you have a stock sheet cut-to-size, cut tolerances apply. To specify other than standard tolerances, please use the Perf-PanlTM quote form to specify the required tolerances.

Margins are the blank (unperforated) area along the edges of the sheet. For stock sheets, the standard is minimum margins along the length and no margins along the width. Cut pieces and special orders will be quoted with “No Margins” only.
